Image processing apparatus and method of communicating with an external apparatus

Abstract

An image processing apparatus capable of fax communication and a method of controlling the image processing apparatus are described. The image processing apparatus has a user interface capable of accepting from a user, in advance of receiving by a network interface a shutdown request, a setting of whether or not to perform shutdown processing based on the received shutdown request when the image processing apparatus is in a state of being connected to a fax line and when fax communication is possible. The image processing apparatus executes, in accordance with the setting accepted in advance from the user by the user interface, the shutdown processing of the image processing apparatus based on the shutdown request received from the external apparatus.

What is claimed is: 
     
       1. An image forming apparatus comprising:
 a network interface; and 
 a controller, having a memory which stores instructions and a processor which executes one or more instructions stored in the memory, configured to:
 receive a shutdown request from an external apparatus via the network interface; 
 determine whether or not the image forming apparatus is connected to a line for fax communication; 
 accept, from a user, a setting of whether or not to perform shutdown processing based on the shutdown request received by the network interface in a case that the image forming apparatus is in a state of being connected to the line; and 
 control whether or not performing shutdown processing of the image forming apparatus based on the shutdown request received by the network interface, 
 
 wherein the controller does not perform the shutdown processing of the image forming apparatus in response to processing of the received shutdown request, in a case of accepting the setting that the shutdown processing of the image forming apparatus is not performed in a case that the image forming apparatus is in the state of being connected to the line, and determining that the image forming apparatus is connected to the line, and 
 wherein the controller transmits information for causing the external apparatus to display a message indicating that the image forming apparatus cannot perform the shutdown processing to the external apparatus in a case where that the shutdown processing of the image forming apparatus is not performed in response to processing of the received shutdown request. 
 
     
     
       2. The image forming apparatus according to  claim 1 , further comprising a connector that connects to the line,
 wherein the controller determines whether or not the image forming apparatus is connected to the line based on a voltage applied to the connector. 
 
     
     
       3. The image forming apparatus according to  claim 1 , wherein the controller transmits screen information to the external apparatus in response to an access from a Web browser of the external apparatus, and the shutdown request is transmitted from the external apparatus in response to an instruction made via a screen displayed on the external apparatus based on the screen information. 
     
     
       4. The image forming apparatus according to  claim 1 , wherein the controller transmits information for causing to display a first message to the external apparatus in the case where the image forming apparatus is connected to the line, and transmits information for causing to display a second message to the external apparatus in the case where the image forming apparatus is not connected to the line. 
     
     
       5. The image forming apparatus according to  claim 1 , wherein the controller determines whether the image forming apparatus is connected to the line in response to the received shutdown request via the network interface from the external apparatus. 
     
     
       6. The image forming apparatus according to  claim 1 ,
 wherein, in a case of that the setting in which the shutdown processing of the image forming apparatus is not performed in case where the image forming apparatus is connected to the line is accepted, the shutdown processing of the image forming apparatus is performed in response to processing of the received shutdown request via the network interface from the external apparatus in a case where the controller determines that the image forming apparatus is not connected to the line. 
 
     
     
       7. The image forming apparatus according to  claim 1 ,
 Wherein, in a case of that the setting in which the shutdown processing of the image forming apparatus is performed in case where the image forming apparatus is connected to the line is accepted, the shutdown processing of the image forming apparatus is performed in response to processing of the received shutdown request via the network interface from the external apparatus. 
 
     
     
       8. The image forming apparatus according to  claim 1 , further comprising:
 a power switch, 
 wherein, in a case of that the setting in which the shutdown processing of the image forming apparatus is not performed in case where the image forming apparatus is connected to the line is accepted, the controller performs the shutdown processing of the image forming apparatus regardless of the setting and whether the image forming apparatus is connected to the line in response to the power switch being pushed. 
 
     
     
       9. The image forming apparatus according to  claim 1 ,
 wherein the setting further includes a setting of whether or not to perform shutdown processing based on the shutdown request received by the network interface in a case that the image forming apparatus is in the state of being connected to the line and the fax communication is possible. 
 
     
     
       10. A control method of an image forming apparatus, the control method comprising:
 receiving a shutdown request from an external apparatus via a network interface; 
 determining whether or not the image forming apparatus is connected to a line for fax communication; 
 accepting, from a user, a setting of whether or not to perform shutdown processing based on the shutdown request received by the network interface in a case that the image forming apparatus is in a state of being connected to the line; 
 controlling whether or not performing shutdown processing of the image forming apparatus based on the shutdown request received by the network interface, wherein the shutdown processing of the image forming apparatus is not performed in response to processing of the received shutdown request, in a case of accepting the setting that the shutdown processing of the image forming apparatus is not performed in a case that the image forming apparatus is in the state of being connected to the line, and determining in the determining that the image forming apparatus is connected to the line; and 
 transmitting information for causing the external apparatus to display a message indicating that the image forming apparatus cannot perform the shutdown processing to the external apparatus in a case where that the shutdown processing of the image forming apparatus is not performed in response to processing of the received shutdown request. 
 
     
     
       11. The control method according to  claim 10 , wherein the image forming apparatus further comprises a connector that connects to the line,
 wherein, in the determining whether the image forming apparatus is connected to the line, it is determined that the image forming apparatus is connected to the line based on a voltage applied to the connector. 
 
     
     
       12. The control method according to  claim 10 , further comprising:
 transmitting screen information to the external apparatus in response to an access from a Web browser of the external apparatus, 
 wherein the shutdown request is transmitted from the external apparatus in response to an instruction made via a screen displayed on the external apparatus based on the screen information. 
 
     
     
       13. The control method according to  claim 10 , further comprising:
 transmitting information for causing to display a first message to the external apparatus via the network interface transmits in the case where the image forming apparatus is connected to the line; and 
 transmitting information for causing to display a second message to the external apparatus in the case where the image forming apparatus is not connected to the line. 
 
     
     
       14. The control method according to  claim 10 , wherein the determining of whether the image forming apparatus is connected to the line is performed in response to processing of the received shutdown request via the network interface.
